Have you ever taken a date to the zoo for the specific purpose of watching the animals mate?

One of my favorite pastimes is getting a couple of lawn chairs, a radio, a cooler full of beers, and heading over the Gorilla Cage at the zoo to watch animals go at it. Everytime I play Marvin Gaye, or Barry White, those Gorillas start making pionate love. None of the dates that accompany me seem to share the same enthusiasm. In fact, it's rare that I get a second date. Is it possible that women aren't into watching other animals make love?
